Advantages:
Reduce Runtime and Response timeMinimize Infrastructure RiskReduced costMulti-tenancy UNLIMITED STORAGEECONOMICAL
DISADVANTAGES OF CLOUD COMPUTING:
TOTALLY INTERNET CONNECTION ORIENTEDREQUIRE HIGH BANDWIDTH OF NET CONNECTIONVENDOR DEPENDANC FOR DATA MAINTENANCE
HIGH BUDGET TO ESTABLISH CLOUD COMPUTING ENVIRONMENTNOT ACCESSIBLE BY EVERYONEHUGE POWER IS REQUIRED
